Step-by-step explanation:
Among the various properties of integers, closure property under addition and subtraction states that the sum or difference of any two integers will always be an integer i.e. if x and y are any two integers, x + y and x − y will also be an integer. Example 1: 3 – 4 = 3 + (−4) = −1; ... The results are integers.

we observe that the sum of two rational no. is also a rational no. . Therefore , we can say that rational no. are closed under addition .
In general, if a and b are two rational no. , then a+b is also a rational no.
